Starting from rest, a 1.9x10-4 kg flea springs straightupward. while the flea is pushing off from the ground, the groundexerts an average upward force of 0.41 n on it. this force does1.8x10-4 j of work on the flea. (a)what is the flea's speed when it leaves the ground? (b) how far upward does the flea move while it ispushing off? ignore both air resistance and the flea's weight.
